well when I bought this scoot I new it was going to get ridden in all types of bad weather. I plan on going as far into the winter as I can stand. Today I got to ride home from work in the rain. Normally the trip takes me about 27 min. I have ridden in a bad storm for a few miles last week and once again this morning. Bike fired right up and I had went about 15 miles when it started losing power. I coasted off to the side of the road and couldnt keep it running. Fuel line is not pinched and the bike acts like its not getting any fuel. I f I hold the gas wide open it will start but will not idle or rev up. I had to call for a ride home. Not making me a scooter fan right now. i do have an open element air filter on and am wondering if it sucked in some water. The starter is turning over fine maybe the ignition got wet. idk. any thoughts would be great. its in the garage drying out. No time to look at it tonite.

This happens to me as well. The filter is clogged with water. Got to either take the filter off and risk riding home, call a ride, or design something to cover the filter element.

Yep, scooters do not like being wet, also the electricals do not like wet.

Yea, that is all it is, the filter is probably soaked, usually the rear wheel will throw a lot of water over the engine. You should make a splash shield to protect the carb and filter from water being thrown from the rear wheel.

I am having the same issue. I am thinking about relocating the air filter to a location above the engine. I have the fenders over the rear tire so it should be a pretty dry area. I am thinking about using some flex pipe (exhaust piping) to move e air filter. I will probably have to retune my carb but it should help.

Water in a carb can be a pain in the a$$ to deal with, if you DID get water in there (and most likely you did) you may want to pull the carb and give it a good cleaning.

yes I am thinking the carb needs to come off. Temps are dropping here so the bike should start leaning out. I should be able to get away with the stock airbox maybe for the winter.
I let the scoot sit over night and tried to start it today. No beans same issue. I need more time to work on it so this weekend it is.

I would say that you have soaked the air filter with water and posably sucked some in the engine also. A free flow air filter is not recommended unless you have a pretty wildly modded engine as the stock box flows well enoigh ever for some pretty high strung 2 strokes. As with a free flow the speed of the air entering and go through the carb slows and is not able to pull the fuel out and atomize it well.

While you're going through the carb this weekend, pull the intake tube and check the reeds. water can damage the reeds and cause it to run the same way, had this happen before, so I know.

OK here's an update. Now im really baffled.
I removed the air filter and drained the gas out of the carb. I started it and it fired up pretty quickly and after it cleaned out it ran great. So I put the stock airbox back on and took off. It wouldnt run. I pulled the airbox and the air horn was really wet with gas. I started it up and it ran great. I put the open element back on and it also died. I pulled it off and put the needle back to the stock position and started it up. It ran fine so I took it down the road with no airfilter and wound it out good. It hit 47mph then I shut it off and coasted to my garage. I pulled the plug and it was nice and carmel colored. Not what I was expecting. I thought it would be wet and black. i had also turned up the oil injection a little when I installed the pipe. so i put the plug back in and restarted it. I noticed that a gas vapor was spewing out of the carb throat and wot. I am lost now. It did not have any of these issues until it got wet. Now it only runs with no air filter. thoughts please.

Have you tried a different air filter? Can you blow out the one you currently have with an air compressor? It may have a thin coat of oil from the road pulled into it restricting it.

I know the symptoms don't add up, but make sure you don't have water in your gas tank.
It may not be your only problem, but it could be causing some of the symptoms.

I've encountered the same problems in the past, you got water in somewhere, just hope you got it out of your gas tank. your quote above is typical (except the air filter being off), the carb throat will always be wet with gas and the filter may have some too. You would think your getting way too much gas, but 2 strokes run like this, even your typical 2 stroke lawn equipment is like this. put the air filter back on and try retuning it, running without an airbox is not good for it. |

Why does everyone forget the air filter oil...
Seriously. get some.
Open/Paper/Foam element air filters DO NOT keep dust, let alone water out of your engine without oiling them.
K&N sells it by the bottle, almost everywhere.
Have a mechanic friend. He put one of these things on his $25,000 Harley. Did not oil it... it died in the rain. Big surprise there. lolz

you dont oil a paper element unless it is specifically designed for that (like the k&n ones) I've oiled hundered of filters and they are all foam ones. Besides there is no way to get inside of this one to oil it if it were foam. Its a use and pitch it filter.

It sounds like the filter is still clogged to a point. I would get a new one, check your carb adjustments, intake manifold gasket, and possibly run a lower # jet. Could be some water still in the crank case area. Either take the cylinder off and blow compresses air in there or run it until it evaporates. Highly doubt there is water in the tank.

well I am ready to unload this damn thing. I cannot get it to run right. I have went thruough 3 plugs rejetted the crap out of it cleaned the carb numerous times. You name it. The only time it runs right is when it is nice outside. Yesterday it ran good and i put 50 miles on it. tonite it wouldnt make it out of my driveway. I give up. I am still leaning towards a a carb issue. The one thing I have noticed is that the slide is scratched and has some rough spots on it. It idles very irratically. I am thinking the slide hangs up. makes it very hard to set the idle and mixture screw when you never know if its idled down or not. I am running out of patience quickly.

"I pulled it off and put the needle back to the stock position and started it up. It ran fine so I took it down the road with no airfilter and wound it out good."
Ok so with the Air cleaner still off it runs OK?
Do you have a fuel filter inline?
You've drained and replaced with fresh fuel?
you've taken air to the electrical? Even a little damp will drive a young man bald when dealing with electrical problems.
Could you adjust the idle B4 the Big rain?

If the air filter got saturated with water try replacing it.
If the carb has bigger than stock jetting, it won't run properly with the stock air box.

still no luck. I oil fouled a plug. I havent been able to ride this pig in 2 weeks. It has been raining almost everyday though. Once again it will run great with no filter on it. If its running and i slip the open element on it loads up and dies. The filter is not clogged or anything. I am supposed to be receiving a new carb any day now. It has a 95 main jet and 40 pilot in right now. I have switched the pilot b ack and fourth a few times and notice no change. I have not tried the stock main again though. I also notice that the bike lays down a bit with the needle in the stock position. As for the idle it has not really idled right since I have owned it. Not sure If i am going to just try and get my $$ back and sell all the parts I bought or just throw the bbk on. My riding season is almost done here now anyway. Just pissed that I have only gotten 360 miles out of this thing and dumped 1400 into it.

i should add that I have checked the intake, fuel line and filter for junk and holes and everything is fine. I never noticed any water on the electrics at all. the only thing I have not checked are the reeds. the reason being that in my experience when reeds go bad starting becomes difficlult and this thing fires right up.

no i havent. the other dy it wouldnt start unless i took my hand and covered up the carb throat. Weird for something running rich. I am sure the af mixture is way off due to the sticking slide. It is def. running rich though. It will run great with a new plug for a few days but othere than that it is nest to impossible to kep it running. I may =try the stock main jet next just to see what it does. I left the key on and the battery went dead. I then found out the kickstarter does not work. geez i am thinking I shouldve just bought a honda.

Just a spark passing between the ears.... does your Carb have a float (OR something like) that is sticking at times? This would cause the "rich flooding effect".
just throwing things out there...

Post by moore716 on Oct 5, 2011 21:07:28 GMT -5
i have checked the flaot for freedom of movement and it seems fine. I have not checked to see if its set properly though. I keep forgetting to bring my calipers home from work to do so. you are correct a float issue will cause you headaches. I had an improperly adjusted float on my yz 125 and kept fouling plugs. Better riders could ride it but I couldnt.
Update. I ordered a new carb for it. I am tired of the dealer jerking me around on this thing. I will check the float and run it with the stock jetting just to see what it does. It should be lean. This will be next week though
